Syntactically, yes, there's no constraint on Text itself. Where the syntactic construct "Text" is used, there are additional constraints (e.g. no "<" in Text used inside normal elements). But more importantly, a syntactic "Element" is restricted by this statement:

# Elements must not contain content that their content model disallows. 

This thus invokes all the content model rules, and the elements that are allowed to contain Text _nodes_ have their own restrictions, in particular:

# Text nodes [...] must not contain U+0000 characters [...]
